are fixedly mounted in brackets 100. The horizontal arms 3 and 4 of these lovers are so connected with bars 7, herein termed co'nr binutionbars, that these gether with the bell-crank levers and t bzirs l constitute parallelogram's. Springs 21 l'uiving one end attached to the frame 23 cause the hell cranks t normally to bear against the common stop 9.2. The key-levers 9 are located transversely above the combination bars T; they are tulcrumed on a common 10 which is fixedly mounted in brackets 102. When one of the keys 11 (Fig. 2) is depressed, its key-lever 9 is-rocked downward and drives those combination bars having t top piece or projection S in the path of the lover. The moved combination bars 7 irnpart to bars 1 a. motion toward the right; the letter carry catches 12 which normally abut against the projections 13 of the switches 2 and rock the letter when their bars are shifted. The upper part 1? of each. of these switches is insulated from the remaindcr and in its normal position bears againstthe contact-piece 15, While after the switch has been changed over it' bears against the contactpiece 16. Current is supplied to these upper parts by the snap rollers 14 which simultaneously secure the switchlevers in their two end positions. The electric circuits in which the contacts 15 and 16 and the snap roller 1-Clore located are not shown in the drawings so as not to complicote the illustration of the present novel features. These circuits, however, appear clearly in Fig. 5 of aforesaid patent, Where in they are also clearly denoted. It may be stated. with regard co-said Fig. 5 that the paper strip 39 appearing therein is located in reality as shown and denoted with. regard to Fig. l of the present application, and was illustrated in said Fig. 5 merely to show that operative connection exists between the levers and the'strip. Likewise inasmuch as in said Fig. 5 the mechanical elements of the InHCiiHlQ (such as for instancev levers 4747 and t8, which are the equivalents of levers 2 in the present application) are illustrated only diagrammatically, the circuits tvhich are made and broken by levers at? i 'and 48 are led for sake'ot' simplicity through the pivotal titres of the levers, whereas in reality as shown inFig. lot the p'resentmachine the current is not supplied to the pivotal axis 20 ofthe'levers 2 but to the separate snap roller 14.; of each lever with which it permanently remains in contact and vthich'electrica-lly is thus of course the full eqliivelent 'of the connection atthe pivotal sxisofi the levers shown in the petent. The arrow points in Fig}. 5 of aforesaid patent, with which the ends of levers is? 48 contact, are in reality the contacts 15, 16 shown in Fig. 1 of the present patent. The projections 8 are so distributed on the combination bars 7 that when any key is depressed the requisite switches 2 are thrown over. F or the machine to Work reliably it is important'that all the switches thrown over by a. key-lever simultaneously break the elec- 7o tric connection With their contact-pieces l5 end sin'iultsncously make it with their con-Q tactpieces lti. To this endythebsrs must move equal distances although, when a key is depressed, the combination bars 7 located neiir the axle 10 of the key-levers moves.- srnullcr distance than those more retrieved therefrom. In order to equalize these clitiera ences I make the horizontal lever-arms 3', 4' of the bell cranks 3 and. 4 longer, the farther 3.; they are removed from the axle 1095 shown in Figs. 1 and 2. As soon as one or more of the switches 2 have been reversed the shaft 2i rotates one revolution. Shaft 2i also. shown for instance in Fig. 8 of eforeseidj patent drives as is shown in Fig. 3 of'theJ present,upplicatic-n shaft 24 .journeled inbrackets by means of cog Wheels103 and 104,. 'On this shaft-is mounted a sprocket- .vheel 105 (Fig. \vhich drives'sha-ft 24"" through the chain 106 and sprockeb'whe'elji 107 mounted on the latter shatt. 1 Shaft 24' is journaled in bearings 108.

- the termination of the bar "382- The paper band 150 is asscd through a guide 34 and a slot in the ar 38 in proximity to the :ptmches 35. When the shaft 24' rotates and rocks the frame '88 downward. the punches participate in this motion- .withont entering into the pa er band. The catches 39 pivotally connected to the punches move past the stop levers 49. These catches are connected by the pivots 39' with the punches 35 and can be rocked toward the right, but are normally held in their extended position 'by springs 40. The stop levers 49 can rock about the axle 53'and are connected by rods 51 with the switches 2. lVhen a switch 'is rocked into its right-hand position it draws over to 'the right the lever 49 connected to it, so that the catch 39 immediately above the moved stop lever 49 bears on it when descending and prevents its punch 35 from moving arther. This punch then unches a hole in the band. In order that he rocked levers 2 can be returned by the cam- 18 into their normal posit-ion before unching o ration, theconnection of the re s 51 with tie levers 2 is made flexible by the interposition of two 's 'rings'62 and 52'; in additional-the faces of t 1e levers 49 which coact with t eeatches 39 are provided with notches 50 for receivin the ends or thecatches. In this manner prevent the levers 2 from returning the levers 49 when they themselves arereturned into-their normal osit-ion. The levels 49 a'rereleased only it en'the 'frame 33 has returned into :its top osition.

'At both sides 0 the set of punches a sprocket wheel '59'is fast on the common s aft -58; the sprockets enter into holes 151 (see Fig. 3) with which the paper band 150 is provided at both edges. The shaft 58 is journaled in the rocking frame plates 33 and carries a ratchet 47 which coacts in such manner with is fixedly pivoted pawl 48 that the ratchet is fed one toot-h whenever the frame 83 returns into its normal osition.

I will now describe the mecianism for actuating the switches 2 by means of a perforated band 150, instead of by keys 11 as previously described, in case such band, already. provided with perforations is. fed through the machine. net on the rocking frame 33 is an axle 64 on which six bellcrank. levers are fulcrumed corresponding in number with the switch levers 2. These levers have noses 85 and carry the bandreading pins 62 pivoted to their right hand arms'at 62. 'These pins are lightly pressed on the one handby springs 63 against. cross bar-tilf'which is provided with recessesfor guidin' the pins, and on the ,other hand by the-beil cranks 65, under the influence of springs 68, ntly upward a inst the paper lmnd'Ii'SO w iich is drawn a cap: over them through a slot 61'. -In the up ermost pcsi-- mount'ed in the upright 111 integral with the machine frame 23, prevents the pins '62 of the levers 65 from contacting with the register band. lVhen the frame 33-descends the right-hand arms of the levers (35 are removed from the stationary rod 60, and the reading pins 62 can enter the band under the influence of the springs 68 on such places where a perforations 152 (Fig. 3) occuis. When the frame 33 together with the axle (i4 descend, as previously described, the lower ends 65 of the bell cranks 65 approach a group of six driving levers 66. These levers 66 can rock about an axle 6T fixed to the brackets 113 and their lower ends 66' are'opposite the stop pins 70 fastened on arms 112 of bars 1. Those bell cranks ()5 whose reading pins 62 have entered into holes 152 in the register band have been rocked far enough thereby to bring their lower arms 06 into alineinent with t-heleft hand arms of the driving levers 66 so that the abut against the latter and by moving bel cranks 66 push the bars 1 to the right. The corres ending switches 2 are thereby reversed. 8n the other hand, so long as one of the reading pins 62 bears against a nonperforated art of the band it does not allow its bel crank 65 to rock far'enough to contact'with the corresponding driving lever 66 and the corresponding-bar =1 and switch 2 remain in their normal positions. The cam 18 and the eccentric 46 are sodesigned that the switch levers 2 which are still reversed are returned in'totheir normal position and released before the bars 1 are s lifted anew by the bell'cranks -66. When the frame 33 IISES the pins are removed from the register band as'soon as the levers 65 again abut against the rod 69; only "then isthe register bandied bythe pawl 48 as previously described.

The manner in which the working shaft 24 is controlled, so far as its stopping and startin through electro-magnetic means, contro ed by the switches 2 is'conc'erned, has been clearly described in my aforesaid patent, where the shaft is denoted with the same reference numeral 24, whereas as already mentioned the switches 2 of the resent application are denoted 47' l7 and 48.

Itis preferable to construct the machine so that the working shaft 24 does not operate when all the switches are in the rest position shown in Fig. 1 of the present application. The consequence is, however that the machine also stops when a non-perforated porticn of the band 150 passes the reading feelers 62. The device embodied in the'rigIht hand portion of the machine shown in igs. 1, 2 and 3 is used .for avoidin such an undesired interruption.

n levers are fast side by side on the shaft 20 about which the switch levers 2 can rock. These levers 80 are so arranged that their pins 81 are opposite, for exam le, the sixth and the'second switch lever.' ast on thesame shaft- 20 is also'a lever 82, in whoseflend isfulcrumed the antifriction roller 83. A spring 84 causes this roller to bear-against'a cam 85 keyed on the working shaft 24. In the course of the rotation of the cam 85 it leaves the lever 82 to the influence of the spring 84, so that this lever drives the shaft 20 and with it the two levers S0. This movement can, however, be prevented. To this end, the end of one of the levers SOYis formed as a nose which can be held by the hook or catch 86. This catch is fast on a shaft 87 carrying atits ends twolevers 88 (only one shown in Fig. 1); These levers are connected together by a rod 89 which runs across the six bell cranks 4 and is pressed lightly against the bell cranks by a sprin 90 attached at one end. to the catch 86. when any one of the bell {cranks 4 is rocked to the right the hook of the catch 86 engages the nose 80 and thereby prevents the two levers 80 from being moved by the spring 84 and from reversing the two switch levers. The cam is keyed in sucha position on the shaft 24 and. m such timed relation to the other elements controlled by this shaft thatthe lever 82 is moved by its spring8+t directly after the displacement of the bars 1 through the mediumof the bell cranks 65 as previously described. When there is no perforated symbol present in the band the bars 1 remam atrest and so would normallythe switches 2; however the two levers 80 then operate and reverse their two switch levers 2 so that the machine starts again and feeds the register band. This will occur as many times, once for each revolution of shaft 24 until perforations in the strip arrive again under the feelers 62. The machine'is so arranged that neither printing or any other 0 oration is brought about by reversing t lose two switch levers.

Adjacent to the catches 39 (Fig. 1) is a bar 54 which is shown in the drawin in the position it occupies when the machine is operated from the keyboard. If it is to be controlled by-the register band, on the contra the-bar 54.- is shifted so far to the rig t that the catches 39 cannot contact with the stop levers 49 and consequently the punches 35 cannot operate.
